14 Claims. (01. 24-2055) This invention relates to slide fasteners and,in particular, to the sliders thereof.

It is an object of this invention to provide a reversible sliderconstruction, for slide fasteners,,which slider may be operated fromeither side of the fastener.

It is a further object of this invention to provide such a sliderconstructicn'wherein opposite sides of the slider areprovided withsimilar pull tab supporting lugs.

It is a further object of this invention to provide detachable slidefastener pull tab constructions, particularly adapted for use on slidersof the above-described type.

These and other objects and advantages of the invention will appear fromthe following descriptiontaken in conjunction with the accompanyingdrawing which forms a part thereof, and will be pointed out in theappended claims.

In the drawing:

Fig. l is a view, in perspective, of a slide astener slider according tothis invention, as applied to a slide fastener;

Fig. 2 is a side view, partly in section and partly in elevation, of theslider of Fig. 1, illustrating the manner in which the detachable pulltab member is attached thereto;

Fig. 3 is a view similar to Fig. 2, but with the pull tab partly insection;

according to Fig. 4, with a second modified form of detachable pull tab;and

Fig. 7 is a perspective view of the pull tab shown in Fig. 6 in itsclosed position.

,In some uses of the slide fastener and, in particular, in their use onreversible garments such as jackets, it isdesirable that the slider maybe operated from opposite sides.

Heretofore, sliders have been manufactured with lugs of different typeat opposite sides of the slider, and with separate pull tabs attached toeach lug. In such constructions, one 01 the pull tabs was of the pinlock type and the other of the non-locking type.

In other constructions, the pull tab was mounted upon a track orretaining slide which extended from one wing or side of the slider, overthe neck or wedge of the slider, and onto the other wing or side of theslider.

In the first of the.above-described constructions, the existence of aswlngable pull tab, at all times, upon the underside of the slider wasextremely disadvantageous inasmuchas it was subject to catching inclothing or the skin of a.

wearer of the garment to which the slide fastener was attached andrendered the slider unit extremely bulky, unwieldy and inconvenient.

In the second of the above-described construc-' tions, the production ofthe track or slide which supported the pull tab was extremely costlyand,

in addition, the track or slide was of such size and configuration as tocatch in the clothing or skin of the wearer in the same manner as didthe extra pull tab on the underside of the slider in the first-describedconstruction, and as to im-' part to the slider unit the above-describeddisadvantages.

These disadvantages are totally obviated according to this invention, byforming. a slider with opposite sides or wings of similar form andprovided with similar pull tab supporting lugs,

tach the pull tab from the, lug at one side of the slider and secure it,detachably to the lug at the opposite side of the slider.

Referring to the drawing in detail, the slide fastener shown in Fig. 1comprises apair of stringers l0 and II, each formed of textile or otherstringer tape l2 having one edge thereof suitably reinforced at I4 andhaving complementary interlocking fastener members 15 secured insuitable manner to the reinforced edge of the stringer tape H. The lowerends of the stringer tapes i0 and II are secured together by suitableknown means such as the bottom stop Ha. While a regular ornon-separating bottom stop is shown, it is, of course, to be understoodthat the principles of this invention are,

applicable to fasteners having other types of bottom stops, orseparating end fittings.

The slider is generally designated l6 and comprises a pair of similarsides or wings I! connected at their upper ends by a wedge or neck l8andprovided with marginal side flanges i9 fastener members l5 and beengaged and disengaged thereby'to open andclo se the fastener in knownmanner.

Each wing i1 is providedwith an upstruck lug 20 of loop form, beneathwhich a locking aperture, or locking pin receiving aperture 28 may,

,optionally, be provided, The wings if being similar, the apertures 2|will be similarly disposed with respect to each wing H or, in otherwords, as seen in Fig. 1, the aperture 2! will appear .to the right ofthe-upper wing ll and the lower aperture 2| will appear to the left ofthe lower wing ll (not shown). The lugs 28 do not project substantiallyfrom the'planes oi the wings I1, and, therefore-do not catch upon the.under garments or skin of a wearer.

Particularly adapted for use 'with the abovedescribed slider bodyconstruction isthe pull tab k shown in Figs. 1 to 3, which is generallydesignated 22. This pull tab is of plate-like form having the upper or.inner end bent over to form form therewith a closed loop. The hookportion .23 and leaf spring member 24 thus form clamping membersensageable with either of lugs 2@.

'One of these members is yieldable or resilient bifurcated form having aplate-like outer end portion 33, from which extends a pair of legs 36having inwardly directed, facing, pivot projections at at theirextremities. Due to the inherent resiliency of the material of the pulltab member 32, the legs 35 are normally biased outwardly of oneanotherbeyond' parallelism.

The outward movement of the legs as is limited by a slidable clampingband or clamping member 85 in the form of a continuous, closed, band.This band as is adapted to rest in a pair of grooves 8? in the outeredges of the legs 36 to release the legs 3d sumciently to allow them tospread to such degree,- as shown in Fig. 5, that the ends of theprojections 35 will be spaced at 1 adistance greater than the width ofthe lugs a hook portion 23. Fixed at one end to the un endthereofconstantly biased outwardly into engagement with the end of thehook portion 23 to ward the inner end thereof into engagement with v 4the grooves 38, the inner ends of the legs 35 arebrought together andthe projections 35 thereof are thrust into the reces'ses'or bores b andmaintained therein.

Whenlt is desired to remove the pull tab 32 from one side of the sliderIto. and to attach it to the opposite side of the slider, it is merelyand the other is non-yieldable; They are-maintained lnclamping positionby the inherent resiliency in the resilient member-243.

' Optionally, where the slide body I6 is provided wlthapertures 2|, asabove described, an upper or inner end extremity of the pull tab member22, adjacent the hook portion 28 is bent downwardly, preferably atsubstantially 90 degrees from the plane of the pull tab member proper,to

. form the locking pin 25 which, in operation, will project through anaperture 2|, as shown in Fig. 3, lockingly to engage interlockingfastener members I! in the fastener member receiving channel of theslider body ll, in the flat or lowermost position of the-pull tab member22. I

when the pull tab 22 is attached to'the lug 20 at one side of the sliderl6 and where it is desired to operate, the slider from the oppositeside, it is merely necessary to bring-the pull tab to the position shownin Fig. 1, press the free end of the spring member-2| toward theadjacent plate-like portion of the pull tab member 22 and then withdrawthe hook portion 23 .and locking pin 25 from below the lug 20 to detachthe pull tab from the slider body. 1

In order toattach the pull tab 22 to the opposite side of theslider, thepull tab is placed in the position of Fig.2 and thrust toward the sliderbody and then pulled downwardly of the slider body to the position ofFig. 3, whereupon the spring member 24' will automatically moveoutwardly to engage the hook portion 23, asv shown in Fig. 3,'detachably to secure the pull tab 22 swingably to the slider body;

In the embodiment illustrated in Figs. 4 and 5,

the slider body liais similar to theabove-de- '7 pivot recesses or bores20b for rotatably, or pivnecessary to thrust the clamping band 38outwardly of the pull tab from the grooves 88, as

shown in Fig. 4, to the grooves 37, whereupon the legs will be spread,as shown in Fig. 5. The projections 35 are then aligned with therecesses orbores 20b and the clamping band thrust inwardly of the pulltab member 32' to engage- I ment with thegrooves 38 whereupon theprojections 35 will be clamped in the recesses or bores 20b, as shown inFig, 4. I

Wherelocking apertures 2| are provided, op-

tionally, as described above, one leg 34 is proingly to engageinterlocking fastener members. 'IS in the channel of the slider Ila.

In the embodiment illustratedin Figs. 6 and "I. the slider body lie andits lugs 20a are similar to the above-described slider body Ito and ofblade-like or plate-like members 43 pivotally connected at M by means ofa rivet, or other pintle means, in such manner that they may move in thesame manner as the blades of a pair ofshears. Inwardlyof the plate-likeportlons of the members 43 is a pair of offset leg portions. 45 whichare coplanar and which terminate in inwardly directed, facingprojections 46 similar to the above-described projections 35 andcooperating with the recesses or bores 20b of the lugs 20a insimilarmanner.

. Spaced from the apertures through-which the pintle means 44 extends,the upper member I; is provided with a downstruck portion 41 which I isadapted. upon alignment of the members I:

otally, receiving suitable pivot projections on a pull tab. As in theconstruction lllustratedin Figs. 1 to 3, the locking apertures 2| may beprovided, optionally, in substantially the same loca-,

' tion in the wings I], as in the-construction of Figs. 1 to' a.

in closed position, as shown in Fig. 7, to engage a complementarydownstruck portion 41 in the lower member 43.

placement of the-members 4! from the closed position when they areplaced in that position,

as shown in Fig. 7. Any, suitable aperture means 48 may be provided inthe plate-like portions of p This engagement of the downstruck portionsll prevents accidental disthe members 43 for alignment in the closedposition to, accommodate suitable tension means. such as ribbons,thongs, or the like.

Where locking apertures II are I provided in the wings ll of the sliderbody I80, as describedabove, one of the leg portions 45 of the members43 is provided with 'a locking pin member 9 which extends through one ofthe apertures 2|, as shown in Fig. 6, in the locked position of theslider, lockingly to engage interlocking fastener members I5 in thechannel of the slider body i612.

When it is desired to remove the pull tab member 42 from one side of theslider body IM and attach it to the other side thereof, the members 43,which are locked in the position of Fig. '7, are moved pivotally apartto the position shownin Fig. 6, whereby toseparate the projections 46thereof sufllclently to permit removal of these projections 48 from thereceiving recesses or bores 20b. The pull tab member 42 is then removedfrom that side of the slider. It may be attached to the opposite side ofthe slider by reverse movement of the members 43 from the position ofFig. 6 to the position of Fig. 7 after one of the projections 46 hasbeen aligned with the recesses or bores 20b.
